To all whom it may concern:

l Be it known that I,JAMEs G. motion,

, a citizen of the United States, residing at Brookville, in the county of Jefferson and `State of Pennsylvania', have invented certain new and useful Improvements in Lubricators, of which the following isa specilication,` reference beingr had to `the accomM panying drawings.

, This inventlon relates to lubricatorsand particularly to a lubricator foruse onrnov` ing parts of machinery, and has for its ob.-

. ject to provide a lubricatorof this character which can be readily operated, and filled without removing the cover.

Another object is to provide `a lubricator of this character which regulates the v, quantity of oil discharged from` the lubricater without interfering with the closing in the valve can be positioned at various clis-` power of the valve. ,u

A further ob'ect of the invention is to provide a lubricator of this character wheretances with respect to the outlet of the lu- `bricator, and wherein the valve can be readily discharged to tightly7 closethe outlet regardless of itsadjusted positlon.

Astill further object is :to provide a lul bricator of this character including an adjustablevalve support, in. which a valve is mounted, said valve being adjustable with the support atcertain times, and movable independently of the support to close the i outlet ofthe lubricator. .pp i p 4 fWith these and other` objects in views-the.

invention consists in the .improvedconstruc-` tion and arrangement .of parts-to l be; hereinl `after more. particularlyI described, fully, claimed and illustrated in the .accompany Figure 1 visa verticalelevation of Aa `bricat-or constructed 1n accordance with embodiment of the invention, p

tothe closed end of the oil cup, and conv into the outlet member. `Proiecting from' the.v lower surface of thewmember is an exf terlorl threaded stem 9 adapted to secure the lu "ricator to the desired part or place.

The .upper portion of the base member 6 wlthm the socket 7 is formedl into a valve seat 10. An orl outlet passage 11 communi cates with the valve seat `and extends through the member 6 and stem 9. The end `portion 4- of the oil cupis closed by means of a cover 12 which is preferably dome-shaped at its upper portion and in-4 cludes an outwardlt1 `projecting annular flange 13, a shoulder 14 being formed at thev junction of the flange with the dome the shoulderbeing intended to engage theend of, the oil cup. The cover is provided with an. inlet openlng 15 which is closed by a valve plate 16 By this means the lubricator can be supplied lwith oil without removing the cover 12. The cover is also providedwith a` centralfopenlng 17 through which the valve mechanism extends. p p

herz-1T, Ihas its endl` adjustably threaded. inthe sockety 'pl-the end portion 20 being threadedin the cover 12. AThe last mentioned end ortionj of the valvesupportsis' provided withf a capl having aV central openingQZ and alnurled periphery. ,JDiSPS6d-fwardly of the end 19 of the valve` Isupport is a pairof opposed elongated shonlders, the lugs terminating in spaced parallel relation to provide a passage 24. The end portion 2()` of the support below the cap 21 is exteriorly threaded and adapted to receive a securing nut 25. After the valvel support has been threaded the desired distance Athrough the cover, the nut 25 is rotated into engagement with the cover to hold the valve support in position and `prevent accidentalmovement. Italso holds the the socket 7.

cover on the oil cup, through the medium of Y gagement with the end 190i the valve suport. p Projecting from the stem 26 in spaced relation to the end 28 of the valve is a pair of opposed lugs 29, adapted at certain times to slide between the shoulders 23, and also to engage said shoulders to hold the valve in `spaced relation with respect to the valve seat. Projecting from the valve stem adjacent the intermediate portion thereof and in spaced relation to the lugs 29 is a pair of opposed lugs 30, adapted to support a spring 3l which surrounds the upper end of the valve stem. lThe other end of the spring is intended to engage the lower surface of Ythe cap 21, the valve stem 26being slidable through the opening 17 of the cap. A nut u 32 is threaded on the upper end of the valve v knob 32 `so as to permit the lugs 29 stem and serves as an operating knob. 4

In use of the device, the valve support may be adjusted either when the valve is 'closed or when opened. If the valve 27 'is engaged with the valve seat 10 of the outlet, and it is desired to discharge a quantity of oil, the stem 26 is rotated by the to pass through the passage 24 between the shoulders'23. This is accomplished by a half turn of the valve stem. I 'When thel lugs 29 pass above the shoulders 23, the valve stem is then released. The lugs 29 will then engage the upper surface of the shoulders 23 and position the valve 27 in spaced relation to the passage 13 according to the adjusted p0-l Y j sition'lof the valve support.

To lncrease the flow of oil when the lubricator is in operation, it is not necessary to close the outlet, but simply loosen the nut 25 and adjust the valve support with respect tov the cover, and socket'by means of the cap 21 thereby moving the valve away from the valveseat. .'vVhen it is desired to close the -lubricator it is not necessary to adjust or interfere with' the adjusted position ofthe valve support, but simply rotate the valve stem 22 so as to permit the lugs 29 to pass through the passage 24 whereupon the extension Vspring will cause the valve 27 to From the foregoing,

close the outlet;

I it will be *readily seen that this invention provides a novel form of lubricator, all parts of which can be readily disassembled for-cleaning or other purposes, and the reservoir filled through the opening 1 5. Furthermore, the quantity of oil to be discharged can be regulated by rotating the valve support within the oil cup so as to cause the valve 27 to move toward or away from the valve seat. This adjustment is possible regardless of whether the lugs 29 are engaged with the shoulders 23 or the valve 27 engaged with the valve seat l0. In addition to this, the valve stem operates independently of the valve support to close the outlet so that the adjusted position of the valve support does not interfere with or decrease the lclosing power of the valve or force of the spring 31. The lubricator can be either opened or closed by a half turn of the valve stem.

The invention having been set forth, what is claimed as new and useful is 1. A lubricator comprising a reservoir, an outlet member carried by one end of the reservoir, a socket member projecting inwardly of the reservoir, said socket having an inlet opening, a valve seat at the bottom of said socket, a valve casing having one end adjustably disposed within said socket, al pair of opposed shoulders in said end of the casing, a valve stem and valve freely mounted in said casing, said stem being movable between the shoulders, lugs projecting from said stem, said lugs being movable into engagement with the shoulders, whereby the valve and valve stem move with the valve casing in the adjustment thereof.

2. A lubricator comprising a reservoir, an outlet member carried by one end of the reservoir, a socket member projecting inwardly of the reservoir, said socket having an inlet opening, a valve seat at the bottom of said socket, a valve casing having one end adjustably disposed within said socket, a pair of opposed shoulders in said end of the casing, a valve stem and valve freely mounted in said casing, said stem being movable between the shoulders, lugs projecting from said stem. said lugs being movable between the shoulders with the stem whereby the valve is permitted to operate independently of the adjustable casing.

3. A lubricator comprising a reservoir, open at one end, a cover for closing said end, an outlet member including an outlet socket carried by the opposite end of the reservoir, a valve casing externally threaded at each end, a cap carried by the first mentioned end of the casing a. pair of opposed shoulders disposed inwardly of the second mentioned end of the casing, the rst mentioned end oi said casing being rotatably mounted in said cover and projecting therethrough, the second mentioned end of said casing being rotatably mounted within the socket, a valve stem freely mounted within said ca sing, one end of said stem projecting through the cap of the casing, the other end projecting beyond the opposite end of the casing, into the socket, the last mentioned end of the stem being provided with a valve, said valve casing away from the outlet at certain times, being movable within the socket between and means for `urging said valve and the the second mentioned 'end-of the casing and first mentioned means toward the outlet 10 the outlet member, means carried by said member for closing the same.
